rrnn irre 'CHAIN-Marceline SPECIFICATION forming part of Letters Patent No. 446,593, dated February 17, 1891. Application filed April 14, 1890. Serial No. 347,860. (No model.)

To all whom, it may concern:

Be it known that I, BENJAMIN S. FREEMAN, Jr., a citizen of the United States, residingat Attleborough Falls, in the county of Bristol and State of Massachusetts, have invented a new and usefullmprovementin Chain-Clasps, of which the following is a specification.

My invention consists in the improved construction of the clasp, as hereinafter fullyset forth.

Figure 1 represents a front view of the chain and clasp. Fig. 2 represents an edge view of the same. Fig. 3 represents an edge view showing the parts disconnected from each other. Fig. 4t represents a longitudinal section. Figs. 5, 6, and 7 are detail drawings illustrating the construction of the parts. Fig. 8 is a sectional view showing a modification.

In the accompanying drawings, A represents the chain, which may be of any approved pattern or construction, and B is the clasp, 'which is formed of two parts a and b, the said parts being each provided with a box or socket c to receive and conceal the end of the chain, the said end being' preferably held within the box or socket by means of a transverse pin d; but other means for attaching the chain to the clasp can be employed.

The part b of the clasp is provided with a lip e, to which is attached a post f, having an enlarged head g, and the base-plate 7i of the part ct is provided with a recess t', adapted to l receive the lip c to prevent the same from l turning, and also with a perforation j, adapted to receive the post f of the part b. Vithin the central perforation 7.: of the disk on, which isheldin the part a above the base-plate 7L, is placed the struck-up spring n, provided with the radiating arms n', which serve to iirmly clasp and hold the post, as shown in Fig. 4,thus` holding the two parts a and together by the frictional contact of the post ,f and spring o2., so that a strong pull in the right direction will serve to effect the convenient disengagement of the parts.

A modification is shown in Fig. S, in which the post itself is made to form the spring, the said post being provided with suitable longitudinal slits o, which will cause the enlarged head g of the post to contract in 'passing through the hole 7i: in the disk m, which disk is held in the part o of the clasp.

The improved clasp so constructed is very desirable as a clasp for a chain bracelet.

l claim as my invention--` A chain-clasp formed in two parts, one part being provided with the lip and a projecting post at right angles therewith having a head, and the other with a recess adapted to receive the lip, and with means for frictionally engaging and holding thehead of the post, substantially as described.
